Use of the Biostimulant Based on the Mycorrhizae Consortium of the <i>Glomeraceae</i> Family in the Field to Improve the Production and Nutritional Status of Maize (<i>Zea mays</i> L.) Plants in Central Benin

Excessive use of mineral fertilizers in maize farming negatively affects farmers’ income and impacts long-term soil health. This study aims to appreciate the effectiveness biostimulant based on native Glomeraceae arbuscular mycorrhizal fungi production uptake phosphorus, nitrogen potassium (Zea mays L.) plants central Benin. The trials were set up a environment with thirty-four producers. experimental design was composed three treatments installed at 34 Three growth parameters evaluated 60 ème days after sowing. Grain yield, nutritional status mycorrhization determined harvest. results showed that + 50% NPK (NPK: azote-phosphore-potassium)_Urea treatment improved height, crown diameter leaf area by 17.85%, 21.79% 28.32% compared absolute control 0.41%, 1.11% 1.46% 100% NPK_Urea treatment, respectively. Similarly, grain yield 45.87% 3.96% treatment. significantly phosphorus plants. With respect uptake, no statistical difference observed between treatments. mycorrhizae strains used root infection We recorded 66% frequency 40.5% intensity mycorrhization. indigenous combined can be as strategy restore health improve productivity
